1,942,357 snns'r wnvnmo MAcnniE George E. Gibbs, Attieboro, Mass; assignor to American Iteenforced Paper Company, Atticboro, Mass., a corporation of Massachusetts Application May 16, 1931. Serial No. 537,806 10 Claims. (01. 242-66) This invention relates to machines for winding sheet material into rollsof predetermined length.
. In winding relatively wide sheet material such as paper into rolls of predetermined length ready for the market it has been proposed heretofore to wind the sheet material onto an arbor to form a roll containing the desired length of material, whereupon the winding operation has been stopped long enough to permit the workmen to sever the roll from the main source of supply, remove the roll from the winding position, and place the leading end of the sheet material around an arbor ready to wind the 'next roll.
These several operations involved in formingsuccessive rolls are time consuming, and the present invention relates to improvements adapted to decrease the work involved in winding successive rolls and also'to increase, the output of the winding machine and insure the accurate winding of the desired length of material upon each roll.
One important feature of the present invention resides in mechanism for-moving an empty arbor into the winding position to. receive the sheet material to be wound thereon.-
Another feature of the-invention resides in means for holding the empty arbor against the sheet material while itis being moved into the winding position so as to hold the material in a taut or stretched condition after it is cut from the finished roll and is being placed around the empty arbor ready to be wound thereupon.
Another feature of the invention resides in mechanism for supporting a knife guiding .bar
and operable to place the bar upon the sheet being wound at the point where the sheet is to be severed, and a further feature resides in measuring means adapted to control the bar positioning mechanism so as. to automatically position the'bar accurately, at the point where it is desired to cut the sheet. I
A further feature resides in power operated means for raising one of the winding rolls 'out of the sheet winding position to facilitate. the removal of a complete roll from the position; i I
. Still a further feature of the invention resides in improvements in the sheet measuring mechanism whereby the measuring means may be easily and quickly adjusted to facilitate the winding of rolls of any desired length.
- .Other features of the invention and hovel 'ts combination of parts in addition to the above will be hereinafter described in connection with the accompanying drawings illustrating good --:pra ctica.l.forms i the invention. a

Fig. 20 is a rear view of the change gear mechanism of Fig. 19;an'd v Fig. 21 is a top plan 'view of the change gear mechanism, the casing being shown in section. The present inventionhas been developed for use upon a slitting and winding-machine emplayed to trim the edges of a wide sheet of ree'nforced paper and'to slit the paper longitudinal- 1y into ,strips of the'desir'ed width, and the in-.
vention has been illustrated in the drawings-in connection witha paper slitting and winding maso v view taken on I 105 chine operating upon reenforced'multiply paper. It is to be understood however, that the features of the present invention are applicable to winding machines broadly with or without the slitting means, andmay be used in connection with winding machines of various constructions and employed to wind different materials.
The winding and slitting machine illustrated in the drawings as having the features'of the present invention associated therewith is provided with the side frames 10 and 11 secured in spaced relation "toeach other by the transversely extending braces or beams 12 and the width of the machine is preferably sufficient to wind at relatively wide sheet of material. The material 13 to be slit onthe present machine and wound into rolls'of a definite predetermined length ready for the market may be supplied from the large roll 14 conveniently wound upon an arbor, or heavy shaft 15, the ends of which are rotatably supported by the uprights -16 positioned at the rear of the winding machine.
The wide sheet material 13 is shown in the drawings as a reenforced sheet such. as paper, having the transversely extending, reenforcing fibers projecting from the edges of the sheet 13- 'as shown in Fig. 1, this being incident to the construction of the multiply reenforced paper. It is desirable to trim the sheet 13 adjacent its side edges so as to provide the sheet of paper with clean, straight edges and give the sheet the desired width. It may also be desirable to slit the sheet 13 longitudinally'into two or more narrower strips and thenwind these strips into rolls R ready for the market. This is accomplished in the construction shown by leading the sheet 13 from the source of supply 14 over the counter operatingroller 17 'rotatably mounted at the rear of the machine upon'the uprights 18 and 19' the tension of the sheet 13. This sheet is then led, upwardly over an idle roller 22, then under 4 the pair of cooperating driving rollers 23 and 24,
which rollers are power driven ina manner to be described. It is desirable to hold the sheet 13 firmly against the surface of the rollers .23
and 24 to facilitate the slitting of the paper and ,27, rotatably. supported by the levers 28 fulcrumed at 29 and the forward ends of which are depressed by the springs 30,-adapted to press the slitters- 27 firmly against the sheet passing around the roller 24 and operable to trim the edges of the sheet, as indicated by 31 in Fig. l, of the drawings and also to slit the sheet 13 into the. desired number of strips. The slitted sheet 13 is passed upwardly around the front power driven roller 24 and is wound upon an arbor 32 which rests in the valley betweenthe rollers 23 and 24 and is held in driving engagement there with. by the upper roller 33', supported bythe uprights 18 and 19 for vertical movement.
The mechanism so far described is not new' with applicant but has been illustrated in the drawings and briefly described to make clear rolls R audit is therefore desirable to'provide braking means associated with the supply roller 14 to retard its rotation and thereby place tension upon the sheet 13. This serves to wind-the sheet tightly about the arbor 32, but when the sheet is out upon a completed roll slack will occur in the sheet 13, extending from the source'of supply 14 about the front driving roller 24, unless means is provided for holding this sheet in a taut stretched condition while a new arbor is being placed inthe valley between the ' rollers 23 and 24 and the sheet is placed about the arbor preparatory to winding a new roll.
Having this. in mind one important feature of the present invention resides in novel means for holding the arbor in engagement with a sheet 13 passing aroundthe, roller 24 from the time im-' mediatelybefore this sheet is severed from the completed roll 32 until the leading portion of this sheet is placed in winding engagement with the new arbor. This is accomplished in the embodiment of the invention illustrated by providing the arbon32 at each 'end with a reduced tip 34, (see Fig. 5) adapted to enter a guiding slot provided at the inner face of each side frame 10 and 11. To accomplish this atip receiving opening 35 is' provided at'each side of the machine adapted to receive a tip 34 so that these tips may move downwardly info the arcuate guid-' ing slots 36. The arbor 32 while inactive normally rests upon the fixed supporting brackets 37, as shown in Figs. 9 and 10, and is adapted to be moved upwardly about the roller 24 into the valley between the rollers 23 and 24, its ends being guided during this movement by the tips I 34 traveling in the guiding slots 36. The arrangement is such that the arbor 32 while in its inactive position shown in dotted lines in Fig. 9 lies out of engagement with the traveling sheet 13, but as it is moved upwardly by operating means to be described, to the position in which it is shown in Fig. 12% is brought into engagement with the sheet 13 passing about the driving roller 24. This is important because the engagement of the arbor 24 at'this point and during its movement from this point into the valley between the rollers is relied upon to hold the sheet 13 taut during the removal of a completed roll from the winding positionandinitiating the next winding operation.
Another important feature of the present invention resides in treadle 'acluatedm'echanism.
adapted to move the arbor 32 from its inactive po-' sition of Fig. 9 to its sheet holding positionof Fig. '12, and later from this position intoihe winding position of Fig. 13. This desirable manipulation'of the a'rbor 32 secured. in the embodiment of the invention shown by providing near the frontof the machine the rocking shaft 38, the opposite ends of which are rotatably sup= ported by the side frames at 39. vThe shaft 38 is provided adjacent each end with a downward-' I the shaft and to the outerend of each lever 40 is pivotally secured at 41 an arcuate upwardly ly extending lever 40 which is rigidly secured to v wardlyalong the ing position. a
arcuate path'36 into, the wind- In the construction shown themeans for rock 'ing the shaft 38 sufficiently to elevate the arbor to the lower end of the downwardly extending 32 to the position in which it is shown in Fig. 12 comprises the foot actuated treadle 43, which is pivotally secured to the fixed bracket 44 and an intermediate portion of this treadle is connected chain 45', the upper end of which is connected to a grooved cam or sheave 46, rigidly secured to to impart a further rocking movement to the shaft'38 to cause the arms 42 to-carry the arbor 32 upwardly about the roller 24 into the winding position.
This further rocking movement is imparted to the shaft 38 by providing the secondfoot operated treadle 48 having connected to an inter-' mediate portion thereof the downwardly extending chain 49, the upper portion of which is connected to the grooved cm or sheave 50. The arrangement is such that when the workman depresses the treadle 48; the arbor 32 will be pushed upwardly by the curved arms 42 in a manner to cause it to roll upon the curved surface of the roller 24 into the winding position and in this -manner the weight of the arbor is utilized to liold the sheet 13 in firm contact with the roller 24 to thereby prevent the sheet from slippingabout this roller and becoming slack. As soon as the treadle 48 is released by the workman and the latch 47 iskicked back to release the treadle. 43 the arbor lifting mechanism just described will return under its own weight to the normal position in which these parts are shown in Fig. 9. The upper end of each curved,'arbor lifting arm 42 is preferably guided by providing the same with a ,r-shaped block adapted to slide in the arcuate guideway 36. I
When a roll R is completed it is desirable to cut ;the sheet 13 delivered thereto at. a point some distance above the surface of the rollers 23; 24, so as to leave a suflicient length of the sheet to facilitate the engagement of the same with the new arbor placed in the valley betweenthe rollers, ;as will be apparent from Figs. 9, 11, and 12.
- In orderto facilitate the cutting of the outermost coil of the sheet wound upon the completed roll R it is desirable to introduce a knife guiding bar 51 between the roll and the outermost coil shown in Fig. 9, to fold the end of the sheet 18 about the arbor 32 and tuck it down around the v arbor as clearly shown in this figure, whereupon the upper roller 33 which is held in a raised position out of thewa'y during the removal of a com-' pleted roll, is lowered into engagement with the new arbon- The winding of the sheet upon this arbor may then be effected .by rotating the rollers 23, 24, and 33.
As above stated the rolls R are wound upon the present machine ready for the market and it is important that these rolls be wound accurately to a predetermined length, say for example, one hundred yards to the roll. It is diflicult for a machine attendant to watch the indicating means, to be described, so that he may stop the winding operation at exactly the right position each time the predetermined length of sheet material has been wound upon the arbor.
length of material wound upona roll and relieve the machine attendant from the exacting duty of controlling the length of the sheet wound upon each roll, another important feature of the present invention resides in measuring means and means automatically controlled thereby for depositing the knife guiding bar upon the sheet 13 at the point where-the sheet is to'be severed so that the barresting upon'the sheet at this point willbe carried upwardly around the com- 'pleted roll under the outermost coil of the'sheet,
as'will'be apparent from Figs. 10 and '11.
In order-to carryout this feature of the inven- ,tion means is, provided for normally holding a knife guiding bar 51 in an inactive position ready to be automatically introduced at the proper time between the roll R and the sheet 13 at the, winding point, as shown in Fig. 10. The mechanism. shown for accomplishing this comprises portion thereof, asshown in Fig. 1, and each arm 54 is provided at its rear end with the pivoted finger 55 provided at its end with-the bar engagknife guiding bar 51. The forward endof each arm 54 is connected by a l-ink 57 to the outer end of a fixed downwardly extending arm or projec tion 58.
The intermediate portion of each -arm 54 isl25 pivotally connected at 59 to the outer end of a crank arm 60, rigidly secured to the rocking shaft 61 disposed near the front of the machine and preferably rotatably'mounted in a flxedhollow therefrom the fixed arms 58.
The arrangement is such that rotation ofthe shaft 61 through part of a revolution serves tomove the bar supportingarms 54 from their nor- .In order to decrease the tendency of error in the 95" -ing jaws 56, adapted to'yieldingly engage the shaft 62 which shaft has extending downwardlylw the bar supporting arms 54 disposed at the op- 115 posite sides of the machine and .at the central 8 0 wound thereupon, as shown in Fig. 11so that a hand knife 52 may readily be passed along the bar 51 to sever the sheet at. this point, as shownin Fig. 11. The completed roll or rolls'R may then .be removed from the winding position by workmen.' grasping the opposite ends of the arbor mal lowered position of Fig. 9 to the raised posltion of Fig. 10 to insert the knife guiding bar between the roll R and sheet 13 to cause this bar to becarried upwardly between: the roll outermost, coil to the position in which it is 6 shown in Fig. 11. The winding operation is p're'f- 1441 p -32 in their hands and lifting the arbor with the rolls thereupon upwardly out of the valley between the winding rollers 23 and 24. This will cause the end of the sheet 13to fall backwardly *over the rear roller 23, as shown in Fig. 12. The
treadle 48 is then depressed to move the empty arbor '32 from the position of Fig. 12 into the position of Fig. 9 whereupon a tucker blade 53 which normally lies upon a supporting shell 54 is engaged by a :workman and manipulated as erably'slowed, down before the bar 51 is deliveredto the winding position and the winding operation is stoppeii when the bar hasbeen carried upwardly around the'roll tosubstahtially the position of Fig. 11 where *the sheet canbe con-14G veniently out along the bar-'.
The desired rockingrnovement is imparte to the shaft -61 by power actuated mecha'n to be described which in turn is controlled b Y measuring mechanism, to be described, and
adapted to cause the bar 51 to be delivered to the winding position as soon 'as a definite prede-v termined amount of material has been 'wound upon the arbor 32.
5 The winding rollers 23, 24, in the construction shown are driven from a motor 63 which is shown in Fig. 1'7 as disposed at the left hand side of the machine and this motor drives a sprocket chain 64 adapted'to .rotate the manually controlled clutch 65,adapted to rotate-the front, roller 24. The rear roller 23 is driven from the front roller 24 and at the same speed by the cooperating gears 66. w
It is desirable to drive the upper roller 33 as well as the lower rollers 23 and 24in order to facilitate, the winding operation and it is found that the winding of the material tightly about the arbor is facilitatedby rotating the upper roller 33 at a slightlyfaster surface speed than the lower rollers 23, 24. The upper roller 33 is driven, in the construction shown, from the right hand side of the'machine viewing Fig. 1; by .pro-
viding this end of the front roller 24 with'a driving gear 67 adapted to drive the gear 68, theouter face of which is provided with beveled teeth adapted to drive the beveled gear 68 mounted upon the upwardly extending vertical shaft 69. This shaft is provided with a slotted keyway and serves to drive the upper beveled gear 70 which meshes with and drives the beveled gear 71 rigid-5 1y secured to the right hand end of the upper roll-. er 33. The gearing just described is such that the upper roller 33 will be rotated at a slightly higher -surface"speed than the lower rollers 23, 24, and a 85 friction slip driving connection 72 is preferably provided between the lower beveled gear 68 and the shaft 69 to relieve the partsjust mentioned from excessive driving strain. I
The upper roller 33 is journaled at its opposite to the uprights 18 and 19 for vertical sliding movement, as shown in Figs. 1 and 18 and these heads are preferably rigidly connected by the beam or roller 33 may gradually be forced upwardly to accommodate the increased size of the roll R and may be moved upwardly out of the way. by means to-be described, when a completed roll is to be removed from the winding position. The weight thereto is partially counter-balanced by the cables 75 which extend upwardly over the grooved pulleys '16, 77, and are provided at their opposite ends with the counter-balancing weights 78 The number of these weights may be varied as desired and the lowermost weight is slidably connected withthe guideway 79.
Having described the driving mechanism for the winding rollers 23, 24, and- 33, the mechanism for rocking the shaft 61 each time a roll has been wound to the desiredsize will now be described. In the construction shown the desired rocking movement is imparted to the shaft '61 by the operating link 80, one end of which is pivotally secured to the outer end of a crank arm 81, rigidly secured to the shaft 61. The opposite end of this link is pivotally secured by the bolt 82 to the operating disk 83 at a' point offset from the axis of this rotating disk. The arrangement, is such that each time the disk '83 is rotated through one complete revolution the desired rocking movement will be imparted to the shaft 61 to flevatesthearms 54 to the position in which they are showrTiiiFig. 10 and then return shoulder 97.
ends in heads '73 which are'slidably connected beams 74, the arrangement being such that theof the sliding heads'73 and parts connected The :disk 83 is normally held against rotation in a predetermined position by friction locking means coniprisinga ball 84 acted uponby the compressed spring 85 mounted within the hollow projections 86 extending upwardly from the gear casing 87. This spring pressed ball 84 is adapted to engage a notch 88 formed in the disk 83 to bring this dis'kto rest in the same positioneach time it has rotated through a complete revolution and to hold the disk from accidental rotation.
The operating disk 83 is rigidly secured to a central shaft 89 journaled in the bearings 90 shown in Fig. 7. This shaft is adapted to be periodically rotated from the hollow gear 91 supported by the ball bearings 92 for rotation about the central shaft 89. h g
Thegear 91 is shown as driven by the gear 67 rigidly secured tothefront roller 24. The mechanism for periodically rotating the central shaft 89 from the gear 91 may constitute clutch mechanism of well known construction and comprises the sleeveorring. 93 having a plurality of slots adapted to receive the small locking rollers 94.
engaged by the latch 98, pivoted at 99 for rocking movement into and out of engagement withthe (See Fi 6.)
The arrangement is such that as longas the latch 98 is held in the position in which it is shown in Fig. 6 the sleeve 93 .is positively locked against rotation and the drivingroliers 94 are prevented from imparting the rotating movement of the gear 91 to the central shaft 89. When. however, the latch 98 is moving out of holding engagement with the shoulder 97, by'means to be described, the sleeve 93 will be rotated slightly under the action of the compressed spring 99 one end of which acts upon the sleeve 93 and the other end against the pin 100 extending outwardly from the. central shaft 89. This slight rotation of the sleeve 93 causes the rollers 94 to effect a locking engagement between the gear 91 and shaft 89 to'rotate the latter through one complete revolution, where upon the latch 98 which hasagain returned to its locking position of Fig. 6 will engage the shoulmaterial has been wound upon the arbor 32 as de- 135 termined-by the counting or measuring mechanism. which will now be described. v
In the construction illustrated in Figs. 1' to 16 inclusive two measuring devices are shown, one for use in winding say, one hundred yards of material upon an arbor, and the other for use in winding' a different number ofyards upon an arbor, and in the modified construction shown in Figs.
19 and 20, change gears are associated'with the measuring mechanism whereby the gears maybe, readily changed to produce rolls; of any. desired length. I 1
The two measuringdevices shown in the COD? struction of Figs. 1 to ,16 inclusive are conveniently j mounted on the upper. transversely extending drive the counter operating gear 109. This gear is operatively connected by the beveled gears 110 to the upwardly extending shaft 111 at the upper end of which areprovided the cooperating bev-' eled gears 112 adapted to drive the shaft 113. (See Fig. 14.)
The shaft 113 through the cooperating gears 114 drives the shaft 115 journaled within the easing 116. Upon the shaft or shafts 115 are loosely mounted two worms 117 and 118 of different pitch, and a sliding clutch 119 provided between these worms may be shiftedin one direction to effect shaft, (see Fig. 3) The pointer just mentioned 4 timedmndinthismanher from the shoulder 97 each the rollers 131, 131 The mech that the finger 128 will move out from between the rotation of 'one worm from the shaft and in the opposite direction to drive the other worm from the shaft. The clutch 119 may be shifted by manually moving the rod 120 in the direction of its length to effect the rotation of either of the, indicating devices from the counter operating roller. The shaft 105 has rigidly secured thereto a worm gear 12l adapted to be driven by the worm 117 and the shaft 107 is similarly driven from the work 118 by the worm gear 122.
In employing the counting or measuring mechanism just described care should be taken to see that the pointer 104 or 106 being used points to the zero positionwhen the sheet 13, is to be wound upon a new arbor, as shown in Fig. 9. If for any reason the pointer should notstand at the zero position at this time it may be readily shifted to this position by squeezing the portions 123 and 124 thereof between the fingers to compress the spreading spring therebetween and thereby release the friction driving connection ,between the pointer and. the pointer rotating is securedto adisk 125 journaled upon the driving shaft 105 and this disk also has secured thereto a projecting finger 126 adapted to operate a counter 12'! which serves to count the number of rolls R wound. The disk 125 has adjustabLv secured thereto a switch closing finger 128' adapted to close a circuit each time the pointer is moved through one complete revolution to thereby excite a solenoid 129 adapted to exert a downward pull upon the rod 130, the upper end of which is connected to the latch 98 above mentime a roll of the desired size is wound and the knife guiding bar; is
. to beinserted. The electric circuit for exciting the solenoid 129 is closed in the construction shown by causing the switch operating finger 128 to pass between the lever supported rollers 131, 131 see Fig. 16. The roller 131 is mounted upon a fixed lever and the roller 131 is-mounted upon a pivoted lever adpted to operate an electric switch in the casing 132 when this lever is actuated by the passage of the finger 128 betweenthe rollers 131, 131 before the winding opera: tion is stopped: This will cut on. the current to -the solenoid 129 and cause the latch 98 to be returned to its active pomtion under the action of the compressed springupon. the rod to the latch 98 is released sm is 11 5" arrest the rotation of the disk 98 as it completes one revolution. Before the electric contact finger reaches the contact elements it prefrably actuates means 133 adapted to ring a bell to warn the machine attendant that it is time to actuate the power driving clutch 65 and slow down the wind ing operation size. I
as the roll approaches the desired Should it be desired to wind a roll having a" different length from that adapted to be wound by the indicator devices 102 and 10s it may then be desirable to employ the change gearmechanism shown in the modified construction of Figs. 19 to 21 inclusive. In this modified construction the worm wheel 121 is rotatably mounted on the shaft 105 and has arearwardly extending hollow hub 134. To this rearwardly extend-.- ing hub is rigidly secured a gear 135 that meshes with and drives a gear 136 which in turn drives the gear 137, these gears being rotatablymounted -within the casing 116. The gear 137 is rigidly 1 secured to and rotates a rearwardly extending shaft journaled in a hub or bearing upon the rear wall of the casing 116, and at the outer end of this shaft is rigidly secured the large gear 138. This large gear meshes with and drives the small gear 139 which is journaled upon a stub shaft carried by the outer end of the adjustable bracket 140. The bracket 140 is mounted 'for rocking movement aboutthe axis of. the driving shaft of the large gear 138 and rotatably supports the gear 139 for movement into driving engagement with agear 141, which is bolted or otherwise removably secured to the shaft 105. It will be seen 1 from the gear construction just described that.
. the pointer operating shaft 105 may be driven at any desired speed relative to' the worm gear 121 by varying the size of the change gears forming the driving connection between the worm gear 121 and shaft 105, and as a result the pointer traveling over the faced the dial 102 may be rotated- "through a complete revolution upon the winding of any desired number of yards of material upon an arbor 32. N
As above stated means is provided for moving the upper roller 33 upwardly away from the roll B so that the latter may be readily removed from the winding position and the winding of anew roll initiated, and since the sliding heads and other parts. provided to rotatably support the upper roller 33 .are relatively heavy it is desirable to provide power operating means for raising this' roller. To this end in the construction .shown an operating shaft 142 is provided extending transversely of the machine below the winding mechanism, and this shaft is driven from the motor- 33 by the chain 143. At the right hand side of the machine viewing Rig. 1 isprovided a clutch 144 adapted'to, drive the sprocket 145 which in turn drives the sprocket chains 146 extending upwardly to the upper sprocket 147' adapted to rotate a'transversely extending shaft 148 journaled at-the upper end of the uprights 18 and 19. This shaft has rigidly secured thereto the gears 149 adapted tic-cooperate with the teeth of the racks 150- supported for vertical sliding movementand the lower. ends of which racks are secured to the'slidin'g heads 73.. The clutch.
144 for controlling the elevation of the roller 33 is controlled-by theftransversely extending rod 151 adapted to'be shifted in ,thedirection of its length by the machine attendant when the roller 33 is'to be .elevated. This roller is preferablyheld in its-elevated position by a dog or other locking means, not shown, which may be manually released when it is desired to lower the roller 33 into its work engaging position.
It will be understood from the foregoing that by employing'mechanical means in accordance liveringthe .knife guiding bar to the winding position at the proper time all rolls will be wound accurately to the proper'size. After a completed roll has been removed from the winding position the arbor 32 may be removed therefrom by hand and placed upon the supports 37- for use in wind-- ing another roll.
